What is an MHTML file?
You can open MHTML files using various web browsers, including Internet Explorer and Chrome, whether you are online or offline. However, MHTML files saved in one web browser may appear differently when opened in another web browser because there is no standardized MHTML format utilized among all browsers.
Programs other than web browsers can also open MHTML web archives. You can use Microsoft Word, Kingsoft Writer, and WizBrother WizHtmlEditor to open the archives.
NOTE: Files with the .mhtml extension are often utilized by cybercriminals to distribute dangerous malware so you should verify the source you received the MHTML file from before opening it.
